i work for a power co and we would use 1/0 2 1/0 aluminum in a flexible conduit. It is fairly inexpensive. |

Payson, Il | How many volts, copper or aluminum, is it single phase? |
|
|
|
| Minimum size for dwelling (house) is 2 AL to serve 100 amps. Any other building 2AL will need to be fused at 90 amps.
Check Voltage drop tables to see if you need to increase the size of the wire to compensate for Voltage drop |

| At that distance I would use 2/0 2/0 2/0. That's. UD triplex, Or go with 2/0 2/0 2/0 #4 that UD quad , That quad will carry a. Saftey ground. Required by national electric code. |

NW Central Ohio | ...you only want to do it once. Go with 2/0, 2/0, 2/0....and you'll never regret it. Aluminum wire loses a lot of conductivity relatively quickly....especially if it gets water in it. Put it in conduit... |

RINGWOOD, IL | My experence in this is I would go with direct burial cable minimum of 3/0 AL reason for a AL as opposed to copper is if if starts to fault copper will keep working and also send power into the ground without you knowing before it faults where AL will just burn through and you will know it now, I also would suggest to put it in pipe that way if ever built or paved over all you need to do if it goes bad is pull it out and back in and with 3/0 AL you have the ability to go up to 200 amp service down the road just my thoughts good luck. |
